I'm having trouble describing it, which makes researching it difficult. The blank space is where it's been deidentified, but the issue is the formula bar rendering multiple times. It "gets stuck" while scrolling and obscures lines like that. Has anyone seen this before? One of our staff said they fixed it in the past just with Office updates, but in this case everything is up to date, including video drivers.

It's not specific to the document, but it is specific to that instance of Excel. It does seem like it's probably memory related, as it has been happening in the afternoon (the user is shutting down at night.) There aren't any other behaviors to indicate a memory problem, or any issues outside of Excel to indicate a video card problem so I'm currently thinking it's Excel.
